The Committee, in its May 30-31 meeting at the Lord's here, also decided against replacing Duckworth-Lewis method by VJD calculation of targets in rain-curtailed matches developed by an Indian, V Jayadevan.
At last year's ICC Cricket Committee meeting, it was decided that batting and bowling powerplays would be taken between the 16th and 40th overs and the teams were required to use two new balls, one from each end. These were aimed at making ODI cricket more attacking, both from a batting and bowling perspective, especially during the middle overs.
The committee at its Lord's meeting said while the use of two new balls had proven successful, the shift of powerplays between 16th and 40th overs had made little impact.
The committee recommended that powerplays be restricted to the first 10 overs plus one five over batting powerplay to be completed by the 40th over. In a non-powerplay over, only four fielders would be allowed outside the 30 yard circle.
They also recommended to increase the number of permitted short pitched deliveries from one to two per over.
"The changes will help enhance what is still an exceptionally popular form of the game. There is though a need to develop a strong identity for the 50-over game distinct from Twenty20 cricket," David Richardson, ICC General Manager
